Topic: Controlling Speed and Time of DC Motor for Magnetic Stirrer (Read 31831 times) previous topic - next topic


Hi Everyone, I'm very new to Arduino and hoping for some help on my project. I'm trying to spin a DC motor from 70 to 255 in 4 equal steps. Ramp to speed over 3 minutes with each step and hold for five minutes. At the fourth step run motor for 15 mins. then stop for 5 mins. Reverse motor direction and repeat the process in reverse and shut off. I have set up a UNO with a L298N. The motor is less than 1 amp. Thanks All.
